Raytheon said Wednesday it submitted its KillerBee unmanned aircraft system in response to the U.S. Navy’s Small Tactical Unmanned Aircraft Systems and Tier II request for proposal. The KillerBee UAS, with its blended-wing aircraft body design, has systems for land or sea launch, recovery and ground control. "KillerBee is the affordable, integrated solution to the U.S. Navy’s need for persistent intelligence, surveillance and reconnaissance in the littoral environment," said Bob Francois, Raytheon Missiles System’s vice president of Advance Missiles and Unmanned Systems.
